Application filed September 26, 1912.

To 112? whom it may concern:

lie it known that we, GEORGE E. tlnuvson and RAY i FERRIS, both citizens or" the United States, und residents of Lebanon and Indianapolis, counties of Boone and Marion, respectively State of Indiana. hove invented :1- certain useful Coin-Controlled Lock; and we do hereby declare that the following is u t'ull clear, and exact description thereof, reference being had to the accompanying din Wings.

The object oi this invention is to provide an improved coincontrolled lock of simplified construction, the action of the parts being positive at all times, thus preventing the lock from being worked from the outside Without first dropping a coin into the slot in the casing.

The feature of the invention lies in the use of :1 locking lever fulcruined Within the casing and having 2t catch on one end normally lying in the path or" movement of a word on the front knob shaft allowing out a slight movement of said knob shaft. and vith the other end of the lever extending into the path of a coin when dropped into the coin chute and adopted to support the coin and be depressed thereby when the bolt is given a. slight inward movement. thus elevating the other end of the lever and moving some out of the path of the Ward on the front knob shaft and allowing it to be turned for Withdrawing the bolt.

lhe nature oi the invention will be undcrstood from the accompanying drawings and the following description and claims.

in thedrswings Figure 1 is a front elevation of our lock. Fig. 2 is a verti'cul'longi- F Elis an elevation of our lock with the front casing removed and showing the iOCl-I- ing lever about to be operated. Fig. 4 is the some as Fig". 3, but showing the locking lever in actuated position. Fig 5 is the same but with portions omitted showing the means for Withdrawing the bolt by the action of the rear ltno'o shaft.

in detail there is shown in the drawings u lled lock having a. rear casing 16/ door 11, and a frontcr up; 12 toe rear resin for concealing the ts of the loc Front and rear 1?; end 14.- extend through front rear casino" it end 12 respectively, tor swing t e bolt to.

knob (not shown) and Within the casing; there is u shoulder engaging the rear easing for preventing; its withdrawal; and there is also it i shuped projection 17 Within the casing, one end. oi which is adapted to engage the crossbar 18 upon the upper bolt rod 19, and the other end adapted. to engage a stop .20 upon the rear casing. The

inner end of said rear knob shaft is oounte bored (see dotted lines in Fig. 2) to receive the reduced end 2.1 of the front knoh shaft id.

The front knob shaft let curries the knob 2'3. and its inner rear end 21 isreduced to extend within the counter-bore 23 of the rear knob shaft 13' before mentioned. A Tshuped plate 24: somewhat similar to the plate 17 is secured to the front lrnoh shaft with the lower end 25 adapted to engage the stop 20, and the upper end 26 adopted to engage the projection 18 on the upper bolt rod. rind in addition there is a. pointed upward projection 27 to the right of the end 26, as shown in Fig. 3, which is spaced away from the hooked upper end 28 of the locking lever 29, and is adapted to he engaged by the some for preventing the turning of the front knob shaft until the coin has been dropped into the slot 30.

The locking leverfzf) before mentioned is fulorumed upon a. pin 31 somewhat below the path of the bolt 15, and its lower end 32 bent toward the. right as seen in Figs. 3 and 5) and lies beneath the curved coin chute 33 and extends into the path of the coin. and when a coin is dropped through said coin chute it will be support and by the lower inner corner or. Qll. bolt ":15. .ils shown in Fig. 3, the upper bolt rod 19 extends through the lever 52$), and spring 341. surroundingthe seid bolt rod and bearing against the bolt on one end and the locking lever on the other. forces said lever to its normal or locking position. limits the left-hand movement lever. A counter 36 rosy he connected through the lever 3'2 and connecting rod 38 with the upper end oi the locking lever 'lhe bolt 15 before mentioned is of the usual outline and has the usual beveled edge (as shown by dotted line 3)., one.

horizontal movementis guided by t is traineone i thereby of which the be t is withdrawn. The lower bolt rod extends through a guide or stop 41 from the rear casing 10, and between. said stop and the bolt a. coiled spring :2 surrounds the rod 40 and tendsto force the bolt to its outer position. The extreme outward movement of the bolt would be stopped, however, by the stop 18 engaging the upper ends of the wards 17 and 24: and forcing the lower ends of said wards against the stop 20.

The operation of our invention is readily understood. When the coin is dropped through the slot 30 it will pass down the chute 33 and be stopped by the lower end 32 of the locking lever 29, and by the corner of the bolt 15, and when the front knob 22 is turned it is allowed free movement until the catch 27 is stopped by the bent end. 28'

of the locking lever, then the bolt 15 will be withdrawn a slight amount, and thus through the coin 43 the lower end of the locking lever will be depressed, the upper end 28 lifted out of the path of movement of the catch 2?, and the knob may be then turned far enough to the left to completely withdraw the bolt. As soon as the front knob is released the coin will drop to the bottom of the case and the locking lever will resume its normal position, and the bolt being forced outward will move the knob back to its normal position, and in doing so the catch 27 will engage the beveled end 28 of the locking lever 29 and pass under it, placing all the parts in their normal position. When the door is released and the bolt strikes against the keeper on the door it will be pressed into the lock, against the action of the spring 4-2 which will shoot it out again after the edge of the bolt has passed the inner edge of the keeper. The action of the inner knob in withdrawing the bolt is entirely independent of the locking inechanism', the upper endof the ward 17 hearing directly against the proiection 18 on the upper bolt rod, and turning the rear knob shaft will cause the Withdrawal of the bolt.

It will be noted that the upper ends of wards 17 and 24. bear against the projection 18, and any movement of the knob shaft will cause a slight movement at least of the bolt; but there is slight clearance between the end of the catch 2? and the catch 28 upon the lockinglever for permitting the necessary free movement of the bolt to actuate the locking lever.

We claim as our invention:

1. A coin controlled lock including a bolt, a knob shaft, means on the knob shaft for withdrawing the bolt, a locking lever adapted to engage said bolt withdrawing means when partially actuated and prevent the complete actuation thereof, and means for guiding and lodging a coin between the bolt and one end of the locking lever so that when the bolt is partially withdrawn it will act through said coin to release said locking lever. v

2. A coin-controlled lock having a bolt, a kn0b-shaft with a projectionthereon adapted to withdraw said bolt, and a spring actuated lever fulcrumed between its ends with one end normally extending into the path of said knob shaft projection, and with the other end of said lever extending into the path of the coin and supporting said coin in the path of said bolt, whereby said bolt will through said coin and said lever move the locking end of said lever out of the path of said knob-shaft projection during the initial withdrawal of said bolt by the free movement of said knob-shaft and thereafter allow the complete withdrawal of the bolt.

3. A coin controlled lock including a, bolt with a. projection therefrom, a knob shaft at right angles to said bolt, a ward on said knob shaft provided with two projections, one of which is adapted to engage the. projection from the bolt and withdraw the belt, a locking lever adapted to engage the other projection on the ward when the ward and bolt are partially operated and prevent further operation, and means for guiding and lodging a coin between the bolt and one end of the locking lever; so that when the bolt is partially withdrawn it will act through said coin to release said look ing lever.

In witness whereof, fixed our signatures in thepresence of the witnesses herein named.
